AbstractWe consider the double field formulation of the closed bosonic string theory, and calculate the Poisson bracket algebra of the symmetry generators governing both general coordinate and local gauge transformations. Parameters of both of these symmetries depend on a double coordinate, defined as a direct sum of the initial and T‐dual coordinate ...

We introduce \textit{Kaestner brackets}, a generalization of biquandle brackets to the case of parity biquandles. This infinite set of quantum enhancements of the biquandle counting invariant for oriented virtual knots and links includes the classical quantum invariants, the quandle and biquandle $2$-cocycle invariants and the classical biquandle ...

Treatment of Gunshot-Related Mandibular Fracture with Splint-Guided Reduction: Case Report
Background/Aim: Gunshot injury-related mandibular fractures often have a complex pattern, characterized by comminution, bone loss, and soft-tissue avulsion. The management is difficult and varies between individual cases.

This study aims to analyze the effect of desensitizing agents on the shear bond strength (SBS) of ceramic brackets after in-office bleaching procedures. Twenty-seven extracted premolars were equally divided into three groups (n = 9).

Audio-digital recordings for surveillance in clinical trials of major depressive disorder
Ratings surveillance is used in clinical trials to assure ratings reliability of site-based scores. One surveillance method employs audio-digital recordings of site-based clinician interviews to obtain remote, site-independent scores for assessment of ...

We review origins and main properties of the most important bracket operations appearing canonically in differential geometry and mathematical physics in the classical, as well as in the supergeometric setting. The review is supplemented by some new concepts and examples.

Poisson brackets and commutator brackets. I [PDF]
A previous result, that for certain problems in Hamiltonian mechanics the commutator bracket is determined by the Poisson bracket, is here extended to include certain problems in Hamiltonian field theory.

The results of clinical testing of photodynamic therapy in the complex treatment of gingivitis, complicating orthodontic treatment with bracket systems. [PDF]
In spite ofa high efficiency, the use of brackets in orthodontic patients can provoke the development of inflammatory processes in marginal periodontal tissues.

On Field Theoretic Generalizations of a Poisson Algebra [PDF]
A few generalizations of a Poisson algebra to field theory canonically formulated in terms of the polymomentum variables are discussed. A graded Poisson bracket on differential forms and an $(n+1)$-ary bracket on functions are considered.

The Hamiltonian description of incompressible fluid ellipsoids [PDF]
We construct the noncanonical Poisson bracket associated with the phase space of first order moments of the velocity field and quadratic moments of the density of a fluid with a free- boundary, constrained by the condition of incompressibility.
